I did that change. The goal was to change @top_builddir@ from "../" to
".."--see the NEWS entry.
The variable ac_top_builddir still has the old value, but will change in the
future. New variable ac_top_build_prefix was introduced; it will keep the
old value forever.
That was my original work. I was forced to do some patch to Autotest, too.
But I don't understand autotest much, thus I wasn't aware of the possibility
of mixing different versions.
I wrote a quick patch; please find it attached to this mail. Is it OK?

Well, I always call tests/autoconf. My installed autoconf 2.59 chokes on
AC_PROG_GREP.
Have a nice day,

* lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
at_top_builddir, for compatibility with older autotest.
* lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
is not set, use at_top_builddir, for compatibility with older
versions of autoconf.
